1.Fertilizer:
As an excellent nitrogen fertilizer ,it can make foliage growth vigorous, improve fruit quality and yield, and enhance crop resistance to disasters, can be used as basal fertilizer, fertilizer and fertilizer.
2.Bulking agent:
In the field of construction and engineering, ammonium sulfate can be used as a bulking agent. It can produce sulfuric acid through hydrolysis, which increases the volume and strength of concrete. Ammonium sulfate expander can be used to make lightweight concrete, thermal insulation, fireproof materials, etc.
3.Water treatment:
Ammonium sulfate can be used in water treatment to help remove hardness substances such as calcium and magnesium from water, which can react with these substances to form soluble calcium sulfate and magnesium sulfate, thereby reducing the formation of limescale.
4.Metalworking:
Ammonium sulfate can be used in metalworking, such as cutting and drilling, and can be used as a lubricant and coolant, thereby reducing friction and heat generation, and preventing metal deformation and damage.
